What to Watch Monday, Oct. 27

'Gossip Girl '(8PM, The CW) Poor Dan Humphrey ... guess he hasn't read the 'Gossip Girl' books, because if he had, he'd know that the new rich kid on the block is one Aaron Rose, destined to be the next boy toy on the arm of one Serena van der Woodsen.

Of course, in the books, Dan is also bisexual, so the TV series will probably never be 100 percent faithful to the book series, but it is true that Aaron ('Stick It' star John Patrick Amedori) is Serena's new Dan.

Meanwhile, Humphrey kid Jenny makes a new friend in the rebellious Agnes, who convinces Little J that she needs to make a bold move with her fashion career, lest Blair's mom squash it before it even begins.

'Heroes'(9PM, NBC) Good guy gone bad (Suresh), baddie (Sylar) with a chance to do good and save his bro (Peter) and a major catfight throwdown (Claire and the returning Elle) ... there's a little something for everyone.

'One Tree Hill'(9PM, The CW) Lucas' cheesy prose not only makes his second novel a hit, but a big Hollywood so-and-so wants to option it for a movie. Only on The CW, kids, only on The CW.

'My Own Worst Enemy'(10PM, NBC)Edward treks off to Mexico to get info on Russian weaponry, but gets double-crossed. So what happens when a guy with dual personalities is double-crossed? We dunno, but it sounds like math might be involved, and we generally try to avoid math of any sort.

'Boston Legal'(10PM, ABC) Murderous Catherine Piper (Betty White) returns to get help from Crane, Poole & Schmidt because, this time, she blew up her doctor. In her defense, she only meant to burn his office down; exploding him was a miscalculation. Elsewhere, Alan and Denny hit a dude ranch.

'Modern Marvels'(8PM, History) It's a Halloween-themed ep, covering everything from fake blood and monster make up to a popular haunted house and the carving o' the jack-o'-lantern.'Jon & Kate Plus 8'(9PM, TLC) The fam gets ready to go to Hawaii for Jon and Kate's wedding vow renewal ceremony, which means Kate has to pack for 10 people. See, this is where the nudists have a leg up on the rest of us.
